WebNov 20, 2024 · As mentioned, I am aware of hclust, and I am currently trying to set up Monocle. Are there any other recommendations for good programs written in R that perform hierarchical clustering? Finally, I was wondering about using a statistical metric such as a Pearson (or Bayesian) correlation to compare how closely related some clusters are. Web10 hours ago · If i don't standardize the data with pearson method, i get different clusters but still decent well divided ones. I know there is a difference if i standardize the data or not. Can somebody help me figuring out why this is happening? I've read in other questions that euclidean and pearson, if standardized, they can be reduced to cosine similarity.
